"We know that sometimes when it gets really physical, people accuse Mesut Ozil of not even turning up for the game.

"It's away, it was going to be tough so he's used his squad the best he can, he changed the system and Mesut Ozil is there on the bench if he needs him. This manager isn't afraid to make tough decisions."

However, Campbell backed Ozil to return for Sunday's visit of Tottenham.

"The challenge is down right there for Mesut Ozil. I think he'll definitely play [in the north London derby]. He's a big-game player," he said.

"Sometimes the mindset is more difficult against the smaller teams because playing against the big teams, that's the one you're motivated for.

"I think there's a bit of mind games going on with the manager and I think he's challenged Mesut Ozil, and I think Ozil will show up."
